Back at his hotel in the capital, Chen Ao couldn't wait to take out the stone. He took out a small fruit knife and carefully cut the outer skin of the stone with all his internal strength. It wasn't until the inside of the stone was exposed that it was darker than the outer skin, and it was changed to a slow scrape. Half an hour later, the contents were fully presented.

A strange stone that was dark and deep, only the size of a goose egg, appeared in Chen Ao's palm. Chen Ao just stared at it for a few seconds, and his mind seemed to be pulled into the boundless depth. After a short period of disorientation, Chen Ao fell to the ground when his mind was almost exhausted. The stone in his hand fell to the ground, and he lay on the ground for more than ten minutes before he recovered. He shook his head like a crack, not daring to rest his eyes on the stone. When I just scraped the stone, my mind was not on the stone. Nothing happened, but when I looked closely, my mind was overconsumed.

"This is the earth marrow jade, it is really peculiar. System absorption" After Chen Ao chattered for a while, he asked the system to absorb this piece of earth chalcedony jade. Immediately, a red light appeared from Chen Ao's hand, and the earth chalcedony jade he was holding in his hand slowly disappeared. After more than ten seconds, only a pile of dust remained in Chen Ao's palm.

Chen Ao threw the dust in his hand into the toilet and flushed it with water. With a bang, a piece of earth cedony jade was gone, even the last residue was gone. Back in the bedroom, Chen Ao immediately opened the system interface and checked the exchange point. Looking at the 3D screen showing the 5009 exchange point in front of him, Chen Ao was so happy that his teeth were about to fall out. A piece of earth chalcedony jade that was almost picked up for nothing was exchanged for 5,000 exchange points. It's a lot of money. Don't say 400 bucks. Even if it's 400 million, Chen Ao has that money. He also bought it.

But now the trouble is coming, and now there are 5000 exchange points. Chen Ao didn't know what to change. I can only ask about the system that has always been cheating.

"System, at this stage. What do I exchange for what is more appropriate for my own strength? Chen Ao thought that if his character exploded, the system suddenly opened up. Maybe you might be able to answer your own question with the mentality of asking.

"I'm sorry, this question must wait for the master's clearance to be upgraded to the intermediate level before I have the right to ask it. I can't answer the question of primary permissions. The cold electronic tone of the system gave Chen Ao a cold answer.

I know that this broken system doesn't hurt me, so I'll do it myself. Chen Ao ignored the system and looked up the exchanged items by himself. See what works best for you. Although he could obviously turn the page automatically with the interface in front of him with his mind, Chen Ao still habitually used his hands to turn the pages in the void.

After looking at it, I decided on the goal I needed to exchange. I put the system away and immediately picked up my mobile phone and booked a ticket. I plan to go home and exchange it again, after all, the last exchange experience gave him a deep memory. If he comes again, it is estimated that this hotel room will be demolished for him.

After booking the air ticket, Chen Ao called the hotel service, and dealt with it casually. I started meditating and practicing until the next day, when I took a plane. Flew directly back to GZ.

As soon as he returned home, as soon as Chen Ao opened the door, he found that his home was full of dust. I had to open the window first to ventilate and clean it casually. I closed the doors and windows and began to exchange items.

Chen Ao summoned the system interface and directly exchanged it for a health booster. At this time, the voice of the system sounded: "The strengthening agent has been used, please prepare the master." It will work after ten seconds, and it will last for one minute. ”

"Isn't it half an hour, why is it only a minute this time?" Chen Ao remembered that the last time he used it, the maintenance time was obviously half an hour. This time it suddenly shortened so much. But before he could figure it out, a wave of heat came out of his body. This time, he didn't feel any discomfort, he just felt warm. Soon the heat was gone again.

Chen Ao felt his body and found that there was basically no change. I can't detect any improvement in my physical fitness, so I can only ask the system of the pit daddy: "System, why did I use a strengthening agent this time, and my body was not strengthened?" ”

"I'm sorry master, this issue has to wait for your clearance to be upgraded to the intermediate level. to be able to answer you, please master work hard to upgrade. ”

"I'm going to go to one of them, and I know that you won't give me an answer if you have a broken system or a cheat. Could it be that the body has developed resistance? Or is my physical fitness getting stronger, and these low-end drugs are no longer of much use? Since there was no reply, Chen Ao could only try it again by himself. Redeemed the booster again. I didn't expect that this time there wasn't even a minute, and the heat in the body was just fleeting. The time for the heat to appear is about a second or two.

Since the strengthening agent was no longer useful, Chen Ao continued to change to a bone strengthening powder. The system's voice also sounded immediately: "The bone powder has been used, please prepare the master." The effect will be reflected after 10 seconds, and the maintenance time will be 10 times. ”

As soon as ten seconds passed, Chen Ao's body felt a tingle. Strange strands of qi suddenly appeared in his body. Bit by bit burrowed into his bones. However, there are always some that don't get in, and they quickly dissipate and fall. These all happened in Chen Ao's body, and Chen Ao couldn't see it. However, he remembered that when he first absorbed the tonic potion, after a trip to Hong Fist. The whole person has a feeling of comfort. Chen Ao was immediately blessed with a soul, and sat on the ground and practiced the Dragon Elephant Prajna Gong. The qi filaments around the bones of Yigong immediately accelerated the speed of absorption. Some of the air filaments that could not penetrate the bones were also forcibly dragged in.

In less than five minutes, Chen Ao stood up. The effect of this medicine, which originally required ten kinds of medicine to absorb, was shortened by half by him, and it was wasted except for a little at the beginning. Everything else was absorbed into him. After two more punches, he felt that the bones of his whole body had strengthened by three points, and the Dragon Elephant Prajna Gong had also made significant progress. Immediately, he exchanged for another bone strengthening powder. But this time, like a health booster, it has no effect at all.

Since these two were useless, Chen Ao could only change to another one, and this time he exchanged another one for Pulse Expansion. As soon as the exchange was finished, Chen Ao sat cross-legged and waited for the effect of the medicine to work. After listening to the system prompt, the effect is twenty minutes later. Another warm current appeared from the dantian. Slowly flow from the dantian to the meridians of the whole body, all the meridians through which the warm current passes. It was moistened, becoming more tenacious and the meridians were slightly expanded.

Chen Ao immediately transported the dragon elephant when the warm current appeared, but it was useless at all. After running it once, I found that it didn't work. He immediately switched to the Arhat Mind Method, and this time the effect was immediate. The warm current follows the trajectory of the Arhat Mind all the way, and the flow speed is getting faster and faster. The effect is also a few points better than that of automatic operation. It took about ten minutes for the effect to fade away.

With the effect, Chen Ao made persistent efforts. In one go, I exchanged five copies of the Pulse Expansion Powder. This time, I redeemed five copies, and it only lasted two minutes. Subsequent redemption will lose its effect. Chen Ao had to set his sights on the enhanced version of the second-level body booster that was ten times more expensive.

Three months later, Chen Ao spent almost all the exchange points, and there were only a dozen points left. There was no change to any medicine that worked on his body. However, relying on the exchange point, Chen Ao used the way of stacking medicine. Forcibly piled up the dragon elephant to the seventh layer. The Arhat Mind Method has also been completed. If it weren't for the breakthrough of the Dragon Elephant Prajna Gong that took time, it wouldn't be a simple **. He may only need a few days.

However, the price of the enhanced potion has increased tenfold, but the effect has not increased tenfold. It's just doubled. However, the number of times it has a strengthening effect on the body has doubled, and I want to use a second-level strengthening agent. Chen Ao used it about eight times before losing its effect. And before he used up all the exchange points for the third-level potion, the effect was still obvious. But now that the exchange points have been spent, I can't do it anymore.

Just like a nouveau riche suddenly becoming poor again, Chen Ao has no mind to practice these days. After a few days of rest, we set off by car. I got the car back that had been repaired a long time ago. He went all the way north again, and this time he specifically looked for places that sold antique jade and the like. It's a pity that a lot of energy was spent, but I didn't find the second piece of earth chalcedony. That's it, all the way to stop and go. I came to the capital again.

I drove all the way directly to Panjiayuan, and then to Panjiayuan. Chen Ao came to the stall where he bought the ground chalcedony jade again, but he didn't expect the boss to remember him. Chen Ao pretended to pick a few stones in front of his stall, and by the way, he scanned all the stones in his stall. Unfortunately, nothing was found this time. I knocked on the side and asked the boss about the source of the purchase of the stone. It's a pity that the boss is also cunning and doesn't reveal a word. Instead, he coaxed Chen to be proud and bought all the stones he had just picked. I talked with the boss for more than an hour, but I saw that the boss never spoke. Chen Ao could only leave the boss's stall with a few useless stones first, and walked around Panjiayuan again, but the result still disappointed him.

In the next few days, Chen Ao went to the boss almost every day to ask. At first, Chen Ao would buy one or two stones first, and then ask the boss for news. But after a few days, it turned out that this boss didn't want to say anything at all. It was just that Chen Ao was interested in the origin of the stone and deliberately hung him. Let him buy stones from his stall so that he can make some money. Chen Ao, who had finally run out of patience, began to ask the boss in a tough tone where he found the stones that Chen Ao bought a few months ago. When you don't say anything, you will flatten him.

The boss finally spoke: "Hmph, you and I are scared." You still want to hit me. I'm telling you, don't say you're just going to hit me. Even if you want to kill me, I'm not afraid. Originally, I was going to buy you a few more stones, and I told you. Now you dare to threaten me. I'm telling you, even if you hit me in the face with a stack of money now, I won't tell you. ”

After a "snap", Chen Ao drove away in the car. All the way in the direction of Tibet. At the stall, the boss was squatting on the ground and counting the money. It's just that there is still a rectangular red mark on the face.
